useful Improvements in Gas-Igniters,

of which the following is ,a description, reference being had to the accompanying drawings, which are a part of this specification.

This invention relates to improvements in means for igniting gas issuing from burners in lamps partic arly adapted for use in connection with ligh ing systems for automobiles motor boats etc., in which gas is stored in tanks under pressure and when used the gas is turned on by openin which control the discharge of gas tanks.

One of the objects of this invention is to rovide a gas ignlter which is automaticin its operation to the extent that when the gas valve with which the tank is provided 15 turned on the gas will be ignited at the burners by means of a secondary circuit of an induction coil or other means for pro.-

- ducing a jump spark between terminals positioned adjacent to each burner.

A further object of this invention is to provide a gas igniter which is simple in construction, and is adapted to be easily attached to the ordinary lighting systems now in general use.

- further object of this invention is to provide a s igniter in which the primary circuit of t e induction coil is comp eted by means of the wrench or lever used in turning the valve controlling the gas serving as a switch.

With the above, and other objects in view, the invention consists of the gas igniter, its parts, and combination of parts, and all equivalents thgreof.

-In the accompanying drawing in which the .same reference characters indicate the same parts in allof the views; Figure 1 is a diagramm'atical view of the complete apparatus shown connected to two burners and to a fragment of a gas tank; Fig. 2 is a side view of a fragment of the gas valve and its operating" wrench or lever andpart of the ignitin attachment connected thereto; Fig. 3 is a ont view of a gas burner with the jump spark terminals connected thereto, part of the burner broken away to show the terminals; Fig. 4 is a side view of the parts valves om the split clamping p The edge of shown in Fig. 3; Fig. 5 is a horizontal section view taken on l1ne 5-5 of Fig. 4; and Fig. 6 is a side view of an ordinary wrench used for turning on the gas valve and which also serves as a switch to close a gap in the primary circuit.

Referring to the drawing the numeral 10 indicates a tank which is adapted to contain an illuminating gas under pressure or it may represent a generating tank adapted to contain calcium carbid, or other gas producing means. The tank is provided with a controlling valve 11 of ordinary construction and its squared end valve stem 12 is adapted to be turned to control the flow of gas by means of a wrench or lever 13 provided therefor.

. A clamping collar 14 provided with a ortion 15 and a reduced end 16 is securely c amped to the stufling nut 17 of the valve by means of a clampin screw 18 engagin the rojecting lips of t e split portion'of t e col ar.

The reduced end 16 of rigidly mounted thereon a fiber insulating bushing 18 and a contact collar '19 surrounding the bushing and extendin beyond the face thereof is astened thereto y screws 29.

tioned with relation to the squared stem 0 the valve that when a wrench or lever is sitioned to engage the valve stem it will a so contact with the insulated contact collar and connect the collar to the stem electrically.

An insulating electrode block 21 adapted to be clamped to each gins burner 22 is provided with jump spar terminals or electrodes 23 which are positioned adjacent to the burner o nin s. The electrode blocks are formed 0 insu ating material and are in two sections 24, 24: which are adapted to be clamped together by a clamping screw 25 which pass loosely through an o ening in one of the sections and is threaded to the other section. with semicircular recesses 26 to accommodate the burner tube. The recesses are located to one side of the center of the block and the clamping screw 25 is located between said recesses and engaging shoulders 27 formed on the sections so that when the clamping screw is tightened the block will be securely clamped to the burner tube. The 'ump spark terminals extend through opfnings provided in. the block and at the otthe contact collar is so pos1- The sections are provided I said valve, an induction tom of the block are bent at right angles and oduce a spark between the spark: termicontinue as electrical conductors. These s for igniting the gas. terminals are held rigidly to the block bycll gas igniter, comprising a valve conmeans of holding screws 28, the heads oi trolling a gas supply, a collar connected to which engage the bent portions of the tern'ri said valve and provided with a Contact colnals, lar insulated therefrom, a burner connected. The bei'itportions' 2901" the terminals to said valve, an induction coil, a primary tend from the electrode blocks to the bi circuit connection between the coil and. the ing posts 30- of the secondary circuit of valve and the contact collar and includin induction coil 31. and. as many burners an electric current supply, jump spark termidesired'inay be included in this circuit; hals connected t the burner W ire s 32 and 83 extend from the hind ing b lock, a secondary posts 34, 8st of the'primary'circuit tgand are connected to the contactcolla'r lt'andj tweenthe coil, and ameans for operating thevalve to the clamping collar 19 respectively. A 'battcry 3 l in cluded in the primarycircuit is control the flow of gas from the supplyand to'simultaneously engage the contact collar adaptedto excite the induction coil when the to complete the primary circuit and produce primary circuit is completed by the wrench. A gas supply pipe 35 extends from the tank to the'burners and'is adapted to supply the burner with gas when the valve is opened.

The operation of the invention is as fol lows: hen it is desired. to light the lamp burners the wrench is positioned on'the squaredend of the valve stem so that the side of the Wrenchisdn contact with the contact collar. In this positionthe gap in the primary circuit is bridged by the wrench and the' ci'rcuit completed through the induction coil and the currentin the secondary coil will be induced thereby and jump across from one spark terminal to' the other and produce a series of sparks, i The wrench is now turned to supply the burners wit s which will be ignited by the sparks. re handle is then removed to prevent waste of current and the burners will continue to burn as long as they are supplied withgas.

From the above description, it will be seen that the burners are automatically lighted when. the gas is turned on.

The apparatus is simple in construction and inexpensive to maintain and maybe easily connected to the ordinary burners now in use. j i

It is'to be understood that this invention is not limited to any specific fornior' an rangementor pal exce t" insofar as such limitations are specified in the claims.
